IMPROVING ACCESS IN NEXT-GENERATION BROADBAND WIRELESS NETWORKS

by Paul Boone , 2010
"... As wireless technologies evolve into the next-generation, an increasing number of users will enjoy the freedom of ubiquitous broadband access. With this widespread use comes several issues that need to be addressed. We introduce and discuss our work on three areas of problem study including efficien ..."
Abstract - Add to MetaCart
efficient access to data, efficient access to the network and prioritized access for emergency responders. First, we propose a hybrid XML forwarding engine for content-based routing. The forwarding engine matches stored policies against incoming XML documents. Our forwarding engine examines the type

Statistically Optimized Minislot Allocation for Initial and Collision Resolution in Hybrid Fiber Coaxial Networks

by unknown authors
"... Abstract—In a two-way hybrid fiber coaxial (HFC) network, the headend broadcasts in downstream channels, whereas all stations share the upstream channels. Hence, collision occurs when multiple stations send their bandwidth requests in a minislot. The headend determines how many minislots to allocate ..."
Abstract - Add to MetaCart
requests in the collision resolution process is estimated by looking up a predetermined table of the most likely number of requests (MLR). In addition, SOMA is modified to reduce the request access delay by relaxing its allocation policy in a specific situation. We use a self-similar traffic model

Efficient Load-Aware Channel Allocation in Wireless Access Networks

by George Athanasiou, Ioannis Broustis, Leandros Tassiulas , 2011
"... Dense deployments of hybrid WLANs result in high levels of interference and low end-user throughput. Many frequency allocation mechanisms for WLANs have been proposed by a large body of previous studies. However, none of these mechanisms considers the load that is carried by APs in terms of channel ..."
Abstract - Add to MetaCart
allocation policies for WLANs in terms of total network throughput by up to 135%.

Contributions to the XDQRAP MAC Protocol over HFC Access Networks

by César Fernàndez, Sebastià Sallent, Eva Vilaginés
"... XDQRAP (eXtended Distributed Queuing Random Access Protocol) MAC protocol is one of many solutions proposed by IEEE 802.14 Working Group in order to define a common background for broadband/multimedia residential services emerging in a near future based on HFC (Hybrid Fiber Coax) access networks. In ..."

VMP: a MAC protocol for EPON-based video-dominated FiWi access networks

by Navid Ghazisaidi, Martin Maier, Senior Member, Martin Reisslein, Senior Member - IEEE Transactions on Broadcasting , 2012
"... Abstract—Optical and wireless network technologies are ex-pected to converge in the near to midterm, giving rise to bimodal fiber-wireless (FiWi) broadband access networks. In triple-play (voice, video, and data) service scenarios for such FiWi access networks, video traffic will likely dominate due ..."
